Title: The Innovations of James G Bearrs
Introduction
James G Bearrs is a notable inventor based in Boise, ID (US). He is recognized for his contributions to the field of thermal ink jet technology. His innovative work has led to the development of a unique patent that enhances the performance of ink jet printheads.
Latest Patents
James G Bearrs holds a patent for a "Thermal ink jet printhead with self-passivating elements." This invention involves a passivation layer that is formed through a reaction between the materials of the ink jet structure and an element that creates a chemically inert, electrically insulating, and thermally conductive compound. The resistor structure may utilize tantalum or tantalum nitride, while the electrical conductors can be made of aluminum. By exposing this resistor-conductor structure to a reactive oxide atmosphere, anodization occurs, resulting in a surface film of aluminum oxide on the aluminum conductor and a surface film of tantalum pentoxide or tantalum oxynitride on the resistor structure.
